The streets in Japan are so clean that even after 10 minutes of walking, your socks are almost white: "How clean are the streets in Japan? I just bought a new pair of socks and now we will check how clean the streets are. One sock, another sock. We go for a 10 minute walk around the city. Time has passed! After ten minutes of walking around Osaka, I wonder if my socks will be any cleaner than after walking around Tokyo. Let's look at the result. Wow! seriously? Oh my god, wow! This is the state the socks reached after ten minutes in Osaka. To be honest, the result is about the same as in Tokyo. That's how clean Osaka is! Write in which city or place I should conduct the next experiment."
